CYLINDER ROTARY BROOM FOR TRAFFIC-LINE LAYING APPARATUS.

Application filed March 29, 1924. Serial No. 702,925.

To all whom it may concern: 7

Be it known that I, FRED L. HANSEN, a citizen of the United States, residing at Plainfield, in the county of Will and State of Illinois, have invented certain new and useful Improvements in Cylinder Rotary Brooms for Trafiic-Line-Laying Apparatus,

of which the following is a specification.

My invention relates to apparatus for laying a traliic-line upon streets or roadways such as are usually utilized for marking streets or roadways to guide trafllc.

of the frame, means nozzle,

In my application for Letters Patent filed January 15, 1924, Serial No. 686,353, I have disclosed such a machine which, in a general way, comprises a supporting frame, means whereby the frame may be'drawn along a roadway, mcans for steering the movement for guiding the steering action, a kettle carried by the frame for containing the substance of which the line is to be laid, a nozzle for laying the line, a pipe line through supplied from the kettle to the nozzle, road cleaning devices carried in advance of the abin carried by the frame and adapted to carry a supply ,of sand and having, a discharge throatway, a distributor chute in communication with the discharge throatway and having its distributing end adjacent the roadway in alignment with the nozzle, distributing pins in said chute for distributing the sand over the line being laid, an agitator device cooperative with the discharge throatway to cause the sand to flow freely therethrough, and means to drive said agitator.

The present invention has for its particular object to provide a the resent invention barrel-type mounted to turn on a horizontal axis with associated means whereby the brush may be angularly adjusted to different positions in a horizontal plane, as well as raised up out of contact with the road when in use More specifically the invention comprises these novel details of construction, combination and arrangement of parts, all of which will he first fully described, then be specifically pointed out in the appendedclaim,

ing in the which the substance is provides a rotary brush 0 the cylinder ofreference being had to the accompanying drawing, in which p Figure 1 is a plan view of a portion of a traflic line laying apparatus embodying my invention, such apparatus being, in large measure, illustrated diagrammatically.

Figure 2 is a side elevation of the structure shown in Figure 1. 4 Figure 3 is an elevation-section view lookdirection of the arrow in Figure 1. Figure adjusting supports for the brush.

Figure 5 is a cross section on line 5-5 thereof.

Figure 6 is a detail vertical section of a modification of the main support for the brush.

Figure 7 is a, cross section on the line 7--7 of Figure of the adj usting supports, parts being in section.

In the drawing, 1 represents the chassis frame of the road vehicle on which the tank 23 that contains the marking fluid islocated and on which the marking nozzle 24 and its associated parts are carried.

Secured to the chassis frame and to the tank is a brush supporting frame consisting of a horizontal lateral support 78, a bracket 80 with a brace 81 and a longitudinal support 79, together witha slotted are plate 82 as clearly indicated in the drawing. q J ournalled in suitably located fixed bearings 62 and 63 beneath the bar 79 is a line shaft 61 driven, in anysuitable way, as by a sprocket 83 and chain 60, forming a suitable rotating part 85 of the vehicle, a take-up roller 84 being provided for the usual purpose.

77 to the brush sustaining frame and which a is a detail elevation of one of the Figure 8 is an enlarged detail view of one so I designates a support which is fixed has an angled extension 77, apertured to 7 7 connected by .ried on the support 77 and is driven by bevel gears 64-65 from the line shaft 61.:

The are plate 82 is curved on a center which lies along the axis of the shaft 67. The support 75 is adjustably secured to the slotted late 82 by a suitable bolt, nuta-nd washer 5, so that the axes of the brush may be positioned in thehorizontal lane in various angles to the direction 0 the travel.

I If found desirable the su port 77 may be made of two arts, 77 and 77, adjustably 1t and slot connections 77 a as indicated in Figures 6 and 7.

68 is a stop collar with a set screw located on the shaft'67. The shaft 67 has a suitable key slot 7 6" and the bevel gear 65 has a suitable key 65 to permit up and down movement of the shaft 67 as the brush is raised or lowered out of or into operative position.

In Figures 6 and 7 I have shown a modified arrangement of the front support for the brush. The support is made in sections 77 and"77 bolt-and slot connected for vertical adjustment to cooperate with the similar structure of the rear support,7475.

By adjusting the arts 69 and 74 up or down and tightening t 1e connection 76, the position of. the brush with respect to the ground may be fixed and determined. By

adjusting the position of the connection between the support 75 and the slotted arc plate 82 the angular position of the brush may be adjusted with respect to the direction of travel. a

By leavin the connection 76 (and the connection 7 if the modification is used) shaft loose enough the brush can rise and .-fall to accommodate itself to road unevenness and the spring action f the vehicle.

f course it is understood that wli'eni driving from place to place with the apparatus out of .use for its intended purpose What I claim is:

pivoted elements, gearing connecting said countershaft with the brush shaft and a driving shaft connected with said countersustaining the rst mentioned brush support. for adjustment in an are having as its center the axis of said countershaft.
